CAB-ROOF.

of the city' of IittsbuifgllZ in lthelcoun of p enn Aave Alleghenyfand.- State o sylvania,`-

invented a new and useful Im rovernent in i Car-Roofs, of which the followingis a specication.

This inventionfrelatesto metal car roofs of aAvell known, type inV which the roof sheets extend crosswise of. thecar and,a re

the hood the end o a roofseamand has a portion 9,

connected at theirside mar ins by upstanding seams. In this tpe o roof, the sheets arezusually held by ood caps or fasteners, which are secured to..the,sidesof1tlie can and overlap and embrace end portionsof the seams. :I Ieretofore such hood caps. o r fasteners-,haves been made in-a single piece without adequate provisiony for more than.,

slight movement of the seams longitudinally of the car. f

The. object of the I,present invention is to permit the roof sheets tomove to a limited` extent to accommodate themselves to the racking and weaving of the car body and to adapt the hood caps or fasteners so that they will follow the movements of the seam lonvitudinall of the car.

'l he invention consists principally in making the hood caps or fasteners in two parts, one of which spans the roof seam and is adapted to slide endwise of the car with said seam without becoming unfastened from the other part.

It also consists in the construction and ar rangement of the parts hereinafter described and claimed.

In the accompanying drawings, in which like symbols are used to designate like parts wherever they appear, Figure 1 is a side elevation of t e eaves portion of a car; Fig. 2 is a cross-section of the same on the line 2-2 of Fig. 1; Figs. 8 and 4 are inner face views of the retaining clip and hood piece, respectively.

My invention is shown in the drawings applied to-a car comprising side plates 1 to `which the side sheathing 2 is secured. Roof sheathing 3 is nailed to the top of the car and at the eaves rests directly upon the side plate and side sheathing. A shallow rabbet is cut in the top side of the eaves edge of the roof boards within which rests the rebent end 4 of the iiashing strip 5. The

The yhood ca fasteners comprise two parts. VOne of t ese'partshereinaftercalled ortion 8,overlaps 4and embraces that extends-downwardly alongside of the fascia. The lower end of this downwardly extending portion has an outwardl or horizontally extending portionlO at t e end of roof sheets. The second piece or member of the fastener'is a wide oke-shaped clip 13 provided with a bolt-ho e 14 in its lower Eortion and having the ends of its arms 15,

ent inwardly and substantially horizontall so as to overlie the longitudinally exten in arms 12 ofthe hood piece.

In tie body portion 'of the yoke is an elon ated horizontal slot 16 of sufficient widt to admit the de ending part 9 of the hood orton 8 and a low it to slide therein. he clip 13 is secured to the side of the car by a carriage bolt 17 which extends through the fascia, sheathing and side plate of the car and is preferably prevented from pivoting or tilting by nails 8, one on each side of the bolt. The retaining clip is also rovicled with inwardly projecting spacing ugs 19, which also tend to prevent it from pivoting or tilting and thereby prevent the mashing of the seams and rebent ends of the flashing and roof sheets. The retaining clip is provided with a semi-circular flanffe 20 located abovel its bolt hole 12 and which acts as a watershed for the head of the bolt 17, thus preventing water from runditions, my Afasteners l ermita-coxisiderablyn` more movement, than as heretofore 'been:v
